CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/623,743, filed on Apr. 13, 2012. The entire disclosure of the above application is incorporated herein by reference.

FIELD

The present disclosure relates to language translation and, more particularly, to techniques for generating translation clusters.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

A bilingual lexicon can generally refer to a vocabulary, e.g., a set of words, in two different languages. Specifically, the bilingual lexicon can relate a word in a first language to one or more words in the second language. One type of bilingual lexicon is a bilingual dictionary. A bilingual dictionary can provide meanings or definitions of words in one (a unidirectional bilingual dictionary) or both (a bidirectional bilingual dictionary) of the first and second languages. Bilingual dictionaries, therefore, can also be referred to as translation dictionaries. In the case of a unidirectional bilingual dictionary, one of the languages may be a source language (spoken/understood by a reader) and the other language may be a target language. For example only, a bilingual dictionary may be a Spanish-English dictionary or a Japanese-English dictionary.

BRIEF DESCRIPTION OF THE DRAWINGS

The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:

FIG. 1 is a diagram of an example computing network including a server according to some implementations of the present disclosure;

FIG. 2 is a functional block diagram of the server of FIG. 1; and

FIG. 3 is a flow diagram of an example technique for generating translation clusters according to some implementations of the present disclosure.

DETAILED DESCRIPTION

Bilingual dictionaries are typically created by one or more human lexicographers, which can be both costly and time consuming. In addition, machine translation may be based on context of a word or words. Accordingly, techniques are presented for generating translation clusters. The techniques include machine translation and clustering, which can be faster and less expensive than manual generation by one or more human lexicographers. Further, the techniques can automatically generate translation clusters without using context. The techniques generally provide for a more useful and user-friendly presentation of potential translations of a word from a source language to a different target language by arranging the potential translations into clusters. The techniques are further described in the paper attached hereto entitled “Unsupervised Translation Sense Clustering,” which is incorporated by reference in its entirety.

Referring now to FIG. 1, an example computing network 100 is illustrated. The computing network 100 can include a server 104 including one or more processors. The server 104 can be configured according to some implementations of the present disclosure. While one server 104 is shown, it should be appreciated that a plurality of servers can be implemented operating in a parallel or distributed architecture. The computing network 100 can also include a computing device 108 (a desktop computer, a laptop computer, a tablet computer, a mobile phone, etc.). The server 104 can be configured for communication with the computing device 108 via a network 112. The network 112 can include a local area network (LAN), a wide area network (WAN), e.g., the Internet, or a combination thereof. The computing device 108 can display information to and/or receive input from a user 116.

Specifically, the user 116 can input a source word in a source language at the computing device 108. In response to a request, e.g., from the user 116, to translate the source word to a target language that is different than the source language, the computing device 108 can transmit the source word to the server 104 via the network 112. In response to receiving the source word, the server 104 can generate one or more translation clusters according to the techniques of the present disclosure (described in detail below). After generating the one or more translation clusters, the server 104 can output the one or more translation clusters. For example, the server 104 can transmit the one or more translation clusters to the computing device 108 via the network 112, and the computing device 108 can display the one or more translation clusters to the user 116.

Referring now to FIG. 2, a functional block diagram of the server 104 is illustrated. The server 104 can be any suitable computing device including a communication device 200, a processor 204, a translation control module 208, a synonym determination module 212, and a clustering control module 216. It should be appreciated that while one processor 204 is shown, the use of the term “processor 204” herein includes a single processor the server 104 as well as two or more processors operating in a parallel or distributed architecture. The server 104 can also include other suitable components, such as memory 220. The processor 204 can wholly or partially execute the various modules of the server 104.

The communication device 200 can be configured for communication between the computing device 108 and the server 104 via the network 112. Specifically, the communication device 200 can receive the source word in the source language from the computing device 108 via the network 112, and the communication device 200 can transmit the one or more translation clusters to the computing device 108 via the network 112. The communication device 200, therefore, can include any suitable components used for communication via the network 112, such as a transceiver. The communication device 200 can be configured for communication via one or more communication mediums, such as wireless (e.g., radio frequency or satellite) communication and/or wired (e.g., Ethernet) communication. It should be appreciated, however, that the communication device 200 can be configured for communication via other suitable communication mediums.

The processor 204 can communicate with and/or control the communication device 200, the translation control module 208, the synonym determination module 212, the clustering control module 216, and the memory 220. As previously described, the processor 204 can wholly or partially execute the various modules of the computing device 108. Specifically, the processor 204 (or processors) can wholly or partially execute the translation control module 208, the synonym determination module 212, and the clustering control module 216. The processor 204 can also control other functions of the computing device 108 including, but not limited to, loading and executing an operating system, controlling communication by the communication device 200 via the network 112, and controlling various operations relating to the memory 220 (storing, searching, retrieving, deleting, etc.). The memory 220 can be any suitable storage medium capable of storing data, searching the data, and deleting the data. For example only, the memory 220 can be non-volatile memory.

The translation control module 208 can determine one or more potential translations for the source word. Each of the potential translations can be in the target language, which is different than the source language. For example, the source language may be Spanish and the target language may be English. The translation control module 208 can determine the one or more potential translations using suitable machine translation techniques. For example, the translation control module 208 may use a language model and/or a translation model in obtaining the one or more potential translations from the source word.

The synonym determination module 212 can determine one or more synonyms for each of the one or more potential translations to obtain a plurality of potential translations. Rather, the plurality of potential translations can include the one or more potential translations and their various synonyms. The synonym determination module 212 can receive the one or more potential translations from the translation control module 208 (or via the processor 204). The synonym determination module 212 can retrieve the synonyms from an external datastore 250. For example, the external datastore 250 can be accessed via the network 112 using the communication device 200. While an external datastore 250 is shown and described herein, it should be appreciated that an internal datastore could also be used. The external datastore 250 can include one or more synonyms for each of a plurality of words in the target language. For example, the external datastore 250 can include all of the synonyms for all of the words in the target language. The synonyms can also be divided into sets. These sets of synonyms can also be referred to as “synsets.” For example, each of the synonyms in a set can have a similar denotation.

Alternatively, the synonym determination module 212 can determine the synonyms itself. The synonym determination module 212 can determine the synonyms for each of the one or more potential translations by applying a clustering algorithm over a portion of the target language using one or more corpora. Specifically, the synonym determination module 212 can determine the synonyms based on usage statistics in the one or more corpora. For example, the one or more corpora can include large monolingual corpora and/or large parallel corpora. This clustering algorithm can be distinct from a clustering algorithm used to determine the one or more translation clusters (a first clustering algorithm, described in detail below) and can therefore be referred to as a second clustering algorithm. The second clustering algorithm can be a K-means clustering algorithm. It should be appreciated, however, that other suitable clustering algorithms can be used. For example, K may be approximately 1000. The selection of K≈1000 may indicate a minimum value of K that produces a desired level of accuracy without unnecessary additional processing. In other words, a value of K=2000 may produce similar accuracy as a value of K=1000, while being more computationally intensive.

The clustering control module 216 can determine the one or more translation clusters using the plurality of potential translations and the first clustering algorithm. The clustering control module 216 can receive the plurality of potential translations from the synonym determination module 212 (or via the processor 204). Each translation cluster can contain all of the plurality of potential translations that have a similar denotation and each of the plurality of translations that have a similar denotation can be included in a specific translation cluster. Each translation cluster can include at least one distinct potential translation of the plurality of potential translations, and the one or more translation clusters can collectively include all of the plurality of potential translations. In other words, the determination of which translation clusters are the correct translation clusters to obtain the one or more translation clusters can be described as being based on the following properties.

First, the determination does not enumerate all denotations of the source word. Rather, denotation distinctions may be made in situations when they affect cross-lingual lexical choice. For example, if a source words has a plurality of denotations but translates the same way regardless of the denotation, then there may be a single appropriate translation cluster. Second, none of the one or more translation clusters should be a superset of another. This criterion of “completeness” encourages larger translation clusters that are easier to interpret, because their unifying denotations can be identified as the intersection of denotations of the translations in the translation cluster. Lastly, the one or more translation clusters do not need to form a partition of the source word translations. Rather, a potential translation can appear in more than one of the one or more translation clusters.

The first clustering algorithm can be defined as follows:

 ← {C ∩ T_(s) : C ∈ ∪_(t∈T) _(s)  

 _(t)}

 ← ∅ for 

 ∈ 

 do if 

 

 ′ ∈ 

 such that 

 ⊂ 

 ′ then add 

 to 

return 

where T_(S) represents the plurality of potential translations, C represents a synset including a set of target-language words,

represents a set of synsets in which a specific potential translation t appears, B represents a source-specific synset, which is a subset of T_(S), β represents a set of source-specific synsets, and G represents the one or more translation clusters for T_(S). It should be appreciated, however, that other suitable clustering algorithms can be used.

After determining the one or more translation clusters, the server 104 can associate a usage example with each translation cluster. The usage examples can be predetermined and can be retrieved by the server 104, e.g., from the external datastore 250. Alternatively, the server 104 can generate the usage examples itself. For example, the server 104 can determine the usage examples by extracting phrase pairs using a parallel corpus. The server 104 can then output the one or more translation clusters (and, if applicable, the one or more usage examples). For example, the server 104 can transmit this information to the computing device 108 via the network 112, and the computing device 108 can display the information to the user 116. In some implementations, this process could be repeated for some or all the words of the source language to automatically generate a bilingual dictionary or a bilingual thesaurus.

For example only, the source word “colocar” in Spanish can be input to the server 104. The server 104 can generate the following translation clusters and usage examples for the source word “colocar” in the English language:

Translation Cluster Denotation Description Usage Example collocate group or chunk together colocar juntas todas los libros in a certain order or collocate all the books place side by side invest, place, make an investment capitales para colocar put capital to invest locate, place assign a location to colocar el número de serie locate the serial number place, position, put into a certain place colocar en un lugar put or abstract location put in a place For example, this layout of the translation clusters, the denotation descriptions, and the usage examples could be displayed to the user 116 at the computing device 108.

Referring now to FIG. 3, an example technique 300 for generating translation clusters is illustrated. The technique 300 begins at 304. At 304, the server 104 can receive a source word in a source language. At 308, the server 104 can determine one or more potential translations for the source word in a target language different than the source language. At 312, the server 104 can determine one or more synonyms for each of the one or more potential translations to obtain a plurality of potential translations. At 316, the server 104 can determine one or more translation clusters using the plurality of potential translations and a first clustering algorithm. Each translation cluster can contain all of the plurality of potential translations that have a similar denotation and each of the plurality of translations that have a similar denotation can be included in a specific translation cluster. Each translation cluster can include at least one distinct potential translation of the plurality of potential translations, and the one or more translation clusters can collectively include all of the plurality of potential translations. At 320, the server 104 can output the one or more translation clusters.

The technique 300 can then end or return to 304 for one or more additional cycles.
